Milk Does Not Do A Body Good – Massive New Study Says

Milk seems to be making its way through various stages of truth, especially within the past couple of years. Like many other examples, what we once thought to be healthy for us to consume is turning out to be the exact opposite.

A large study coming from researchers at the Uppsala University in Sweden found that drinking milk led to an increased mortality rate and actually made bones more prone to fracturing, not less.(1)

The study was recently published in the peer reviewed British Medical Journal, and was specifically conducted to examine whether high milk consumption is associated with mortality and fractures in both men and women.

The study took place across three different counties in Sweden, and used data from two large Swedish cohorts, one with 61,433 women aged approximately 39-74 years old and one with 45, 339 men aged approximately 45-79 years old. They were all administered food frequency questionnaires. The study used “multivariable survival models” that were “applied to determine the association between milk consumption and time to mortality and fracture.

The results were as follows:

“During a mean follow-up of 20.1 years, 15 541 women died and 17 252 had a fracture, of whom 4259 had a hip fracture. In the male cohort with a mean follow-up of 11.2 years, 10 112 men died and 5066 had a fracture, with 1166 hip fracture cases. In women the adjusted mortality hazard ratio for three or more glasses of milk a day compared with less than one glass a day was 1.93 (95% confidence interval 1.80 to 2.06). For every glass of milk, the adjusted hazard ratio of all cause mortality was 1.15 (1.13 to 1.17) in women and 1.03 (1.01 to 1.04) in men. For every glass of milk in women no reduction was observed in fracture risk with higher milk consumption for any fracture (1.02, 1.00 to 1.04) or for hip fracture (1.09, 1.05 to 1.13). The corresponding adjusted hazard ratios in men were 1.01 (0.99 to 1.03) and 1.03 (0.99 to 1.07). In subsamples of two additional cohorts, one in males and one in females, a positive association was seen between milk intake and both urine 8-iso-PGF2α (a biomarker of oxidative stress) and serum interleukin 6 (a main inflammatory biomarker).” (1)

The study concluded that high milk intake was associated with higher mortality in one cohort of women and in another cohort of men, and with higher fracture incidence in women. It also concluded:
